Racing Ralph evo, Rocket Ron evo or other for xc racing?

As the title says..

What would you guys recommend ( only people who actually know the answer please! by this i mean unbiased! )

So which is faster rolling? or which just works better for xc racing?

I was also thinking going 2.1 rather then my usual 2.25 as i'm guessing they would roll faster still??

Also is there any other options I should maybe choose over these 2?

Here's a general comparison (based upon my experience) -
Ralphs:
-More cornering grip
-More durable
-Heavier
-Less traction

Rons:
-Less cornering grip
-Less durable (ridiculously skinny sidewall, ripped a couple in the south downs)
-Lighter (50g ish an end)
-More traction

I've found the Ralphs to be marginally quicker in terms of rolling resistance, but I dare say the difference is negligible to most.

I have (only one Ron in working order) a set of each, and have used Ralphs (F+R) all year round (on my main bike), which have suitable 95% of the time.

According to this study ( http://www.mtbonline.co.za/downloads/Ro ... trated.pdf ), you'd be wrong to say a narrower tyre is faster, I think it makes little difference, particularly if you run low pressure like myself.

Basically if I was told 'you're only allowed one set of tyres all year round', I'd pick the Ralphs, for said reasons.

Just the answer I was after.. Great stuff thank you.

Furious fred ;-) did you race friday night?

Rushmore

Well, I went for some 2.4 racing Ralph evos, feels a bit wrong going for wide tyres to race with, but science doesn't lie..

@ pilch, yes I did... Wasn't a big fan of the course though.. Only 1 technical stretch which was too easy and the rest pretty much Tarmac... Total Roadies course, not mtb rider course .

Mallory park this Friday though! Much better!!!
