MTB slick tire comparison--difference in speed

My Performance Fast City tires are getting near replacement, but I'm
considering the Ritchey Tom Slick tires.

Here's the details:

Performance Fast City (26 x 1.25) (90 psi max)
Ritchey Tom Slick (26 x 1.0) (100 psi max)

Would the Tom Slick tires be noticeably faster since they are narrower
and have a higher psi rating? Or is the difference too small to
really matter?

Thanks

All other things being equal, the wider tyre has the lower rolling
resistance. At MTB speeds, the small aerodynamic advantage of a
narrower tyre is likey to be outweighed by this factor, as is the
small pressure differential if you run both tyres at their recommended
maximum. You might also consider Conti GP MTB 26x1 120psi if you go
really fast and want to emphasise aerodymanics, or Schwalbe Big Apple
26x2.0 70psi if you want low rolling resistance; Schwalbe claim the
same rolling resistance from this tyre at 30psi as a 1.25" tyre at
60psi.

Another "fast" tire to consider is the Avocet Fasgrip 26x1.25. It measures
about 32mm wide, the Avocet is "slick" that is fast, comfortable and very
durable tire. You can find it for about $20 each. For road/street riding, I
pump it up to 95psi, no problem. Try it!

The Avocets are good as well as Specialized FatBoy 1.25 tires.

I have used 1.4 Tom Slicks and they are also fast. They are a little
narrower than their 1.4 size would indicate.

I tried 1.0 tires before, but found I did not like them on MTBs. They
had several drawbacks: 1)may not fit well with wider MTB rims, 2)offer
little protection from less than perfect roads, 3)Do not handle as
well (maybe rider position/weight distribution difference from MTB to
Road bike?), 4)ride a whole lot rougher, especially on a hard tail
MTB, 5)not really any faster in real world use (in my experience the
1.25's are faster)

Stick with the 1.25 Avocetts or Specialized. By the way, the
Performance 1.25s are not as fast. They are not the same quality,
flat a lot more, and don't handle as well.
