Ive found the maxxis ignitor to behave much the same way as the Fire XC (my preferred 26er tyre before Im moved to 29er)
Very predictable grip all the way over when banking. No squirming (like nasty michelins) and no surprising breakaways.
Small Block 8s are great on hardpack, but a bit draggy on the road IMO.
A mate runs some Stouts (weigh a Kg each! 😮 ) which give pheneomenal traction on the single speed and keep you glued to the floor at the front, but they are like riding through treacle.
Currently Im running a WTB werewolf 2.55 on the front and find it surprisingly good despite the low profile tread – I wouldnt run it in winter though.
Ive not tried the Bontys but I know a lot of people love them – Ive never need to as I like the tyres Ive got.
WTB werewolfs and exiwolfs can be got for £20 each from WIlliams Cycles in cheltenham (they will post out)
I use singlespeed.nl for rare stuff.
You can also get quite a few bonty tyres from Craig (?) at Swinnerton Cycles now.
