I live in SK where monster fish are the norm and I would say there really is no need for a 10" I've yet to ever see someone not get a fish up through a 8" hole. I would say that it's probably 75% 8" 5% 6" and 20% 10"
Thanks for the feedback guys! Sounds like worth dabbing with 10" also! To make adjustable design would make cumbersome and clumsy. If I do sell them ill post them on here. if I don't make them ill show them so ya'll can try design.
You cant sell a homemade item here without being a site sponsor... which if I remember correctly is around $300 a year... or something like that, I was quoted for a site sponsorship on the MFF site a few years ago and I think it was close to $300.
