I’d throw Cove Hummer and Brodie Holeshot Ti into the pot as well.
Avoid anything made by Lynskey – that’s the path to misery and madness.
The Cove Hummer is made by Lynskey (i’ve got one), and the new Cove Hummer 650B is being made by Lynksey as well, now’t wrong wi Lynskey built as far as i can see? – perhaps they’re not as boutique as some TI frames/builders but they do know their stuff and their warranty dept is very good.
I dunno who makes the Brodie but it does look like a fantastic frame, it was a toss-up between a Cove Hummer and a Brodie for myself, I choose a Cove and i’m very happy.
