[CQ-Contest] Scatter modes on 10 - Success or Failure

[Hammond, Rob EU-Pencoed]

I'm not a propagation expert but I have noticed propagation via scatter on
10 most times I've operated on that band. 
When I had a high 6 element Yagi on 6 Meters , There was another guy living
6 miles away who was always active. There was a huge mountain between us,
some 6 miles across & 1800ft High with us both tucked either side in
adjacent valleys but if we both beamed in the same direction, south or
north, 80% of the time, we could work but signals were very "fluttery". 
So on 10 ?
========
I've heard though that to work scatter modes successfully on 10, you need to
be running HP & have a good antenna system. As my license is for 100W only I
wonder what type of success I might expect.
  This year in the CQ WW SSB , M6T was very strong to me on 10M but I know
there is no direct path from that area of the UK as there's about 20 Miles
worth of Mountains between us ( & about 150 miles after that ) & I live in a
valley, but I wasted a good couple of minutes ( due to in-experience )
trying to work them on 10&15. 
 For this weekend I'm operating from the top of one of the highest local
mountains with beautiful sloping ground in most directions & a high
monobander + vertical.  I wonder your opinions on whether my 100W will
possibly work via scatter modes or will I be wasting my evenings when I
could be tucked up in bed awaiting the next morning to operate ??

Cheers
