I try to get them wore out a bit and then get their head up the hole [...] I roll the sleeve up and get my hand down in the hole and scoop them out. My 2 cents
You can buy a smaller treble hook gaf ready to go for under $10
Not really a low price option but if you're into rod building these kits might be fun.http://www.mudhole.com/Rod-Building/Gaff-Building
We have never lost a trout using that gaff I built. I like it because it is narrow and hooks are small but very sharp.The key is to hold the gaff down in the hole as the fish is being brought up into the hole. As his head comes up slid the gaff over and right under the gill plate and lift. Works perfectly.
