"I was thinking of investing in a set of High Rollers (2.35"
IMO they're slower than 2.1" Kenda Nevegal DTCs front and rear
Both are faster than 2.25" Advantage 60a's though
"Specialized Eskar Controls, similar tread to the HR, cheaper, not too heavy"
Visually much closer tread to Advantages IMO (though sort of similar to HRs also)
CRC have folding 2.35" 60a HRs for £23 atm. Eskars are also £23 but are sual compond (55/65a) unlike a single (60a) compound HR. Wire HRs are £19 but more like 800g
folding 60a HRs are 646*/695g. Eskars are 700g (claimed)
I've not ridden an eskar so I've no idea how fast they roll or how they handle (they're on my mental 'would like to buy' list though, along with minions and many many more .. )
2.1" Nevegal DTC folding**/2.35" High Roller 60a folding**/etc and a 2.1" Crossmark (62a or 70a, wire or folding) ought to make a decent summer compromise I reckon
*according to JustRidingAlongs actual tyre weights pags
**Just to keep the wieght down. Plus DTC (50/60a) is only available on folding versions
