I'm on the market for a new saddle after my current one started creaking and eventually snapped the end of the rail off.

Been trying to pick up a second hand SLR but not having much luck, anything else i can try? i've considered a charge spoon buts is a bit on the heavy side for my race hardtail

Charge Knife perhaps? Much the same as a Spoon, only slimmer and lighter with titanium rails. Slightly less comfy though but not badly.

charge knife

Don't dislike the look of that, Anyone compare it to a selle italia SLR? considering an SLR-XP is £15 more expensive

Charge Knife is great. I have one on my full susser and an SLR-XP on my hardtail. The knife is a lot comfier although the SLR is a bit lighter. The increase in comfort is worth more than the weight loss though I reckon.

SDG Bel Air £20 from Merlin.

Already got a bel air on my intense and don't like it to actually "sit" on. Hence it's on my 4x bike.
