Pre-punched Boge (LR) Carto recommendations?

[FogMatic]

Hi all,
I would rather not hassle with punching my own and am wondering what those of you with more experience have found and where. I'm assuming there are differences between vendors as far as number of holes/size of hole(s)--what are your preferences?

Thanks!
John

I use Mom & Pops Boge pre-punched. They have 3 holes and are good for 50/50 and thicker jooses.
I tried some 70/30 & 80/20, but 3 holes are to much and I experienced flooding and some leakage.
