Precision Tips (medium)
Blackjack (medium)
I've played with a few different tips, these two are my favorite. As for the reason, the latter of the two are what the cue maker suggests and I tried and loved them, great tips! The Precision, was recommend by a friend and seen many reviews on here, so I decided to give a layered tip a try.
I would recommend both of the tips I have listed.
On another note, in my experience tips are not magic, try a few until you find one that does what you need it to do and leave it alone, keep it shaped and move on. When I came back to playing after a few years off I got caught up in trying every tip made, because I thought it was the tips fault for MY shortcomings in the game. As it turns out, instead of wasting loads of money searching for the magic tip I should have focused on fundamentals and table time. Just my opinion, good luck.
