prop question for experts (fezz, alf,etc)

prop question for experts (fezz, alf,etc) can get any other colt to score first td at 20-1. pinnacle has +528. can get mike bell for 1st saints td @ 16-1, pinnacle has +625. given that they are such longshots and will probably lose anyway, what unit would you play on them. I am getting almost a 400% margin on 1 bet and almost 250% on another.

Not sure, I didn't price these haystack/needle props Sorry, I'm no help

I played them for about 20% of my average nfl side bet.

Tough to catch these type of props....I do know a capper that has Bell @ 25-1
