I've owned the Fuel now for a year.. well, just over.. So i'm tempted to do some swapping.

So the what and the why.

They're all fairly similar in terms of reach, with 6mm difference between the longest (Sentinel) and shortest (Fuel).
Sentinel is the slackest head angle with the Hightower having the highest stack (only by 3mm over the Sentinel).
The 2 i don't own are both carbon frames if that changes anything, possibly a weight thing as they'll deffo build up lighter than the Fuel. the Fuel is quite a heavy frame in the Gen6 in it's own right.
I don't know if either will 'change' a great deal in terms of what i can or can't do, or ride or can't ride.. possibly/probably not.... But both could be an interesting change maybe.
In terms of costs.
Keeping the Fuel £0
Hightower frame £1250
Sentinel full bike £1600
The Sentinel is a 21/22, the Higher is a 24 but 23 model and the Fuel was 25 bought but 23 model.
If i get the Sentinel i'd sell the Fuel, it only cost me £1400 on C2W and is worth that all day. If i got the Hightower i'd use the bits off the Fuel and then sell the Fuel frame...
