Mt.Snowdon or Cadair Idris?

Im trying to list rides to do in 2012 and am considering the ranger track at Snowdon or Cadair Idris. Anyone done both, which is better and what time of year is best for Snowdon?

Mt.Snowdon?

How about both? Then you’ll know for yourself

Snowdon depends on if there is snow up there
I went up late march this year (the day before the train opened for the year) and was very little snow about. Was great
I’ve walked up in previous years in late march and its been too snowy from just past the halfway house

Else Ocotber-ish

Else push/carry up within ban season and ride down as the clock strikes 5pm?
