I thought ox springs were square and titan round.

I know in direct comparison to the hw97 square spring the titan I put in my mates gun was a lot quieter and smoother with no vibe.

I think they put a low friction type coating on the titans, well this one had a coating anyway.

The farmers lad on a farm I shoot once put an ox spring in his gun, and it just made it very jumpy on firing not what I would call a tuned set up at all, probably why Ive always shot more than him on his own land.

I think the best thing to do is either buy a standard spring for your gun or a quality round one and like said the v mach type are top quality.
