Probably not exactly what you’re looking for, but here’s an interesting chassidic source strongly favoring bekius (from R’ Nachman of Breslov, Sichos Haran #76):
“The best way to learn Torah is by studying fairly rapidly without analyzing every single detail. Study briskly and simply: seek to understand each thing in its own context without confusing yourself about how it relates to other subjects.
If there is something you do not understand, it is usually best not to dwell on it for too long. Keep going. In most cases you will eventually come to understand it in the light of what follows.
When you study, the main thing is to read the words aloud and in order. Understanding will then come of itself. Do not confuse yourself by trying to comprehend everything at once. You will have much difficulty and end up understanding nothing.
Simply focus your mind on what you are studying, reading the words in their correct order and with enthusiasm. Understanding will come of itself. What you do not understand at first, you will comprehend later. Even if there are things you cannot fully understand, this is unimportant because broad knowledge outweighs everything else.
By studying rapidly you will absorb a great quantity and you will be able to review each work many times. What you did not understand at first you will grasp the second or third time round, and eventually you will understand everything that it is possible to understand.
By following this path you will complete many volumes and have a better comprehension than one who is overly precise. Such a person can become very confused and may even come to abandon his studies completely, ending up with nothing.
Accustom yourself to learn quickly without too much attention to detail. This way you will truly acquire the Torah and cover enormous ground. You will be able to complete the Talmud, Codes, Bible, Midrash, Zohar and other Kabalistic texts and all the other sacred works.
It is unnecessary to review everything immediately. It is better to complete each volume as rapidly as possible from beginning to end and then to review the entire work as a whole.
Don’t be anxious if you are unable to complete everything. One can be a faithful Jew even without being able to learn at all. One can be a Tzaddik even without being a scholar. It is true that deep perception cannot be attained without Talmudic scholarship, yet even the simplest Jew can be a Tzaddik. ‘You are not obliged to complete the work, but neither are you at liberty to desist from it'(Avot 2:16).”
