Well, I bought the RSL because I found a virtually brand new one second hand and I couldn't be happier. I do race, but would never race the RSL because when you crash it (like happens endlessly in crit races in the UK) it will hurt much more than just road rash. But I do ride aggressively and I ride a lot of sportives and ride in the Alps and Pyranees every year, and the RSL does it all. I train on it 5 days a week, only stop when its raining, and only then because I have my winter wheels on my Look 585 which is also a brilliant bike and is some winter steed !!
As for grouppo, SRAM Red PF30, they are brilliant, SRAM Red complete grouppo except for Ciamillo Gravitas brakeset which although a pig to set up are stunning. I run three wheelsets on it, Reynolds MV32CUL, SRAM S30AL Race and Fulcrum Racing Zeros with CULT bearings, it rides brilliantly on all of them, it is a bike that feels "zingy" it just seems to want to go !!! When you pedal it almost pushes you forward, I have never owned a bike that makes me sad because I don't feel like I'd ever want to sell it until the RSL, I will never get rid of it. Its harsher than other Ti bikes I've ridden, but you never feel beaten up, rather just at one with the road. When I was buying, I got down to just two in my list, the RSL and the IF TiFLW, it was a close run thing but the Moots is the better long term option in my mind as there is no carbon to deteriorate but they were both just streets ahead of anything else that I had ridden and at the time of buying my quiver included a Look 595, 585, Colnago C50 and Master Olympic, Cannondale Six, Super Six, System Six and CAAD 7. I have now sold everything and am left with the RSL, the 585, the Master Olympic and the CAAD7, and I cannot imagine any bike improving on those, but the RSL is simply head and shoulders over the rest, I never ride anything else, and its only time until the rest of them go too.
Let me put it this way, if it got run over and destroyed tomorrow, I would call Moots and order another immediately, but I'd go custom and I'd put 1 cm more on the headtube, other than its perfect.
Buy one, if you can afford it, you will never be disappointed, don't worry about PF30, its flawless and that bike ROCKS !!!
