Thanks all for the replies
I'm still not sure what side of the "no such thing as a bad hill" yet as my lockdown legs (and extra timber) complain with anything more than a few flights of stairs but I'm determined this year to bag double digits.
To those suggesting lower level walks, I totally get that and I did swither with doing so but....the temptation to build on last week's first bagging in two years was too strong and I've decided on Carn na Caim & A'Bhuidheanach Beag. Should be manageable and the route profile appears fairly forgiving.
Regarding Mayar and Driesh (already bagged), I do feel Corrie Fee in glorious sun made that experience better
Now I just hope Perth Tiso has OL51 in stock and parking in the lay-by goes ok!
