TLDR > see title... With intent for lays

  1. Invest time 30mins-1hr with a girl then try to pull home and if they decline, next

Or

  1. Spend shorter time (max 15 minutes) kissing grinding etc - then get their number with intent to get them on a date in future rather than same night lay.

What in your experiences is a better use of time?

I always apply the first strategy but if I strike out with all 3 (approx) girls having last minute resistance or cock block friends (usually guys), I feel like I've wasted my time.
