You are not forced to use small hooks in the age of the hair rig. Matching hook size to bait size is a tactic from general coarse fishing days when baits were not hair rigged. If you use some kind of bouyancy aid like cork you can use as big a hook as you want. I'm happy to use 4 or even 2 with 20mm baits. If you're concerned with visibility balance your rig with the hook on the deck. Even a tiny paternoster whoops,I meant chod (or is it khod) could have the hook off the deck and the fish could well ignore it's presence.
Side hooked boilies required a big, wider gaped hook just to work effectively,size 2 and even 1/0 had been used.
Small hooks may penetrate easier but bigguns tend to stay in and are strong. It's all about matching the weight of the bait.
I tried 10 mm boilies once,they kept splitting.
