There are a few of us lo pro folks who know how great it can work, good to see, though seemed there was way more discussion of it 10-12 years ago on here when everyone had to custom rig their lo pro setups with nothing but chain readily available, and people were machining down 8 pin .404 sprockets to 3/8LP, and putting LP nose sprockets on their bars. I'm a relative latecomer, I was interested for awhile but didn't jump in til I could get the whole bar/sprocket/chain package from the UK and understood it better. Now I've learned enough I've been able to share some useful knowledge with the UK people to help them with their offerings.
I was going to try a 10 pin LP sprocket I bought from 6K/Danzco on my 880 w the GB 48" lo pro bar, to up the speed and diminish the torque as much as possible, but thought better of getting the bar for now since I ran into issues with 28"+ hardwood with full comp on my 36" GB bar. Too many cutters engaged, not enough chip clearance. Was good still I began maxing out the bar, and then it only works at all when the chain is razor sharp. Lightning Performance gave me a good baseline for any chain when he told me past 18-20 cutters engaged, he found cutting really started to slow down significantly, and at that point you want to move to skip to get chips clearing better. I have about 21 cutters engaged with lo pro when I'm at 30" in a log. I want to try a custom "double skip" grind on lo pro that worked well for me in .404 on one 42" chain I tried it on, but haven't gotten around to it yet. Half as many cutters as full comp (taking off alternate pairs of teeth), whereas I think skip is 3/4 the number of full comp cutters, and hyperskip is 1/4 the number of cutters of full comp. I should try lo pro skip first, but it's a slightly rare beast and I think my "double skip" is more efficient and just as good a finish as skip. It's a lot less complicated than the Granberg grind and there's nothing to screw up like a bad grind from Granberg potentially could. Produced a beautiful finish in .404 on 30-32" white oak slabs. Now I have my 87cc Stihls rebuilt right, if I do get the GB 48" bar, I know they would be able to pull a 48" lo pro bar with double skip no problem so I won't bother trying to run it on the 880 and risk snapping chain too easily with the torque of the big beast. And maybe get a 9 pin LP sprocket from 6K instead as the 10 pin seems maybe a little too big for proper chain feed into the bar tail. But since the 48" GB bar is an 880 mount, I'm sure I'd try at least once w the 10 pin in the big saw just to see how it went. The 48" GB lo pro bars hardly cost any more than an off brand 50-52" 3/8 bar these days so they're not bad value.
