Dan. I haven't read the rest of the thread so this may be going over old ground, but much or all really of the ridge is semi-technical ground where you will be moving unroped for speed bit still can't afford to take a tumble - effectively you're soloing for most of it anyway. There's are several short pitches which being up to about HS in difficulty are usually climbed with a rope, most (all?) of which are easily bypassed if you don't fancy them. There are a number of down climbs/abseils which aren't so easily bypassed which you might want to take a rope for even if you are soloing.
Personally speaking, though I have climbed regularly to a reasonable standard and have soloed more routes than I've led, since I suffer from a bit of vertigo I can't say I particularly enjoyed soloing the lowly moderately graded In Pinn - notwithstanding that apparently some non climbers merrily dance up it with a bike on their backs! It's definitely horses for courses and something that only you will know if you're happy with.
If I were to solo if tomorrow, I'd solo it and skip out the TD Gap/In Pinn/King's Chimney etc., but I guess I have the excuse of having done then already.
Get a blue sky day and the whole thing will feel easier by orders of magnitude than it does when the weather is shite.
Best of luck.
