probably this is not a matter of choosing. In these cases we can assume the faith should be so strong in order some Dhamma teaching notions can appear integrated like happens when we think in the consequences after arising of panna.
I understand that before the stream entry, the faith is an ingredient always existing in different degrees in all the followers. And in some cases this can become the main catalyzer. At all, Faith is another way of knowledge able to surpass delusion precisely by denying it. Conviction and discernment are not so different at all.
I ignore the details about how panna and faith are related at those moments, it would be interesting to know from an Abhidhamma analysis.
“Who is a person Dhamma follower? Any person who
practising for the realisation of the fruit of stream entry, whose wisdom faculty is in excess, who is lead by wisdom and for whose wisdom is the precursor, develops the Noble path. Such person is called Dhamma follower. The person practicing for the fruit of stream entry is Dhamma follower, standing in the fruit he is View -attainer.”
“Who is a person Faith- follower? Any person who
practising for the realisation of the fruit of stream entry, whose faith faculty is in excess, who is lead by faith and for whom faith is the precursor, develops the Noble path. Such person is called Faith follower. The person practising for the fruit of stream entry is Faith follower, standing in the fruit he is liberated by faith.”
Ab. Pp. 7
The definition of Dhamma follower or Faith follower is given to individuals at the time of the Noble path.
They will be called Dhamma follower or Faith follower depending their dominant faculty at the time of the path.
Before that, for someone practising vipassanā both faculties will develop, and it may not be easy to identify one’ s strongest faculty.
And here i shall quote the Visuddhimagga, which gives confirmation, and a method to know how one was Faith follower at the time of the path and liberated by Faith afterwards, or Dhamma-follower at the time of the Path and View-attainer afterward:
“yo hi aniccato manasikaronto adhimokkhabahulo saddhindriyaṃ paṭilabhati, so sotāpattimaggakkhaṇe saddhānusārī hoti. sesesu sattasu ṭhānesu saddhāvimutto.”
" When he (i. e, the yogi at vipassanā advanced level) focus the mind to the impermanence (of the sankhārā) with strong resolution he acquires the faith faculty, he is Faith follower at the time of the path of stream-entry. And in the 7 others instances
( fruit of stream entry and 3 other path fruitions) he becomes Liberated by faith. "
" When he focus the mind to the non -self (of the sankhārā) with strong knowledge he acquires the wisdom faculty, he is View-attainer at the time of the path of stream-entry. And in the 6 others instances also (fruit of stream entry and 2 other path fruitions with path of Arahantship) and at the highest fruit (Arahantship) he becomes Liberated by wisdom. "
From Vis,2, saṅkhārupekkhāñāṇakathā
Visuddhimagga itself quotes Patisambidhāmagga, which explains the same thing.
The case of the kāyasakkhi (Body-witness) and ubhatobhāgavimutto (Both-way liberated) is also discussed, according to his attainment of arūpa jhāna, focus on suffering of the formations before the path, and concentration faculty as stronger.
This is key, and remember that Path lasts one mind moment. It is already an attainment and it is for sure to result in fruition in the next mind moment.
This is also a great question among Dvipitakins, some think the path is not for one moment, because of some suttas…They think the Noble path may last hours, days weeks and son on.
One time we had discussion about it with a monk, a friend who is dvipatakin. He mentioned it.
Then i asked to him:
" What about the many cases in the suttas of individuals who attained stream entry suddenly by just hearing a discourse, sometimes extremely short?
Their path was only for a short moment, right? "
Then he was quite voiceless… But later he did the hypothesis of a path with not the same amount of time according to individuals… But he admitted that even with the suttas only, it is impossible to reject a short, mind-moment Noble path.
“Upon hearing the first two lines, there arose in the wanderer Upatissa the dust-free, stainless vision of the Dhamma - the first glimpse of the Deathless, the path of Stream-entry - and to the ending of the last two lines he already listened as a stream-enterer”.
