HSS vs TCT

Hi all,

I've just started on Harold Halls 'Lathework - complete course'. I
bought a set of TCT lathe tools from Chronos at the weekend, cos I
didn't really have a proper set. There was a choice between the TCT and
the HSS, but reading another thread here, have I made the wrong choice?

Is HSS better for making light cuts, like for finishing? I've been
running the TCT at high speed, with lots of oil, but not getting a very
good finish. They seem OK for removing lots of metal.

What kind of grinding wheel should I be using to sharpen TCT? I've
heard it ought to be a soft green wheel?

I was also looking at MaryPoppins' tipped tools on eBay. Might they be
fun?

Cheers,

Ed
