Yeah, and SS isn't going to cut it here!
I'll add a narrower Aggressor to my shopping cart
Consider the Dissector too, it has a slightly lower rolling resistance than the Aggressor and is a touch lighter in a 29 x 2.4WT 3C EXO Maxx Terra. Or, keep the Aggressor; dropping 100g isn't really going to be that noticable and they still roll well with a touch more air.
After sifting through the last 5 pages, the guts of your dilemma seem to be rooted in your level of fitness and a lack of available time to do something about it. Neither of which is your fault - young kids take up a lot of time and energy. Don't take it out on the bike though, a Prime is a great quiver killer, and I reckon more of a trail bike than the current crop of AM steeds, most of which are pushing into the 140-150mm travel range as geo and suspension tunes get better and better. Changing bikes isn't going to magically give you more time to get out riding, and as
@beeb buried in his verbiage (
), you'll likely take a hit finanically and end up regretting selling the Prime.
In my humble opinion, I would suggest that now is exactly the wrong time to be sinking more money into the Prime to lighten it up, make it more spritely, whatever. Changing the dropouts to the neutral setting is a no brainer, that will help with the pedal strikes and put you in the 66° HTA range which is pretty steep, considering trail/AM bikes are around 64-65° these days. Mess with tyre, fork and shock pressures to firm it up a bit and you'll have spent nothing and have a more playful bike. Then find time to ride it more.
Disclosure - I have a 150/135mm bike and when I'm fit, it's a blast. If I've been unable to ride regularly though, I don't gel with it either - it feels sluggish and awkward, but I know that's me, not the bike. That's why I have a hardtail (Chameleon) as a second bike - it's about the same weight as the dually, but with all that 'underbiked edginess' that
@beeb describes - it never fails to put a grin on my face, no matter how shitty I am feeling when I roll up to the trails. An hour on that thing does wonders for your fitness too, as you don't want to be seated too much!
