What trebles do you use on the Shad rap or that style of crank bait let’s say #7 Shad rap size 

Rapala #7 came with stock #6 hooks. You could also try the kvd triple grip, 1-x,2-x, to up one size in hook, to a #4. Otherwise maybe Owner   STX-36 or Owner STX-38 ZoeWire. I use both, and find they are excellent hooks. My first choice will always be Owner, but the kvds work well and are cheaper.

Rapala stock hooks are VMC, which are fine.  I like to replace with Owner ST-36 for this sized bait.
