@SatNavSaysStraightOn Mo is one amazing rider,
Having sorted the sp/cad, I think the h.r. is u.s. tried a new battery and tried scanning just not picking it up, either a fault in the strap or the sensor, I can't afford £11 just to try a strap and then have to get a new sensor and strap so I will just have to get a whole new thing, then try the sender on the new strap if that works than I know for the future, but it will mean putting getting of the 705 another month, and I could do with as I have a referral to a clinic in Seacroft, Leeds and I really dont know the area, however that referral can be at any time but the nature of it, it is likely to be sometime yet, but you know sods law.
I know what you mean about gearing I have been finding the same, and some are really subtle 16-17 is the most subtle
Edit
Talking of saddles, I have offset mine slightly to the left as you look along the top tube from the rear of the bike, I have yet to decide on the best angle, as this seems to alleviate a pain/numbness I get in my right leg, I think I am maybe trapping a nerve, I suffered a compression injury in this leg (and broken a foot bone), when I started cycling I had problems with a sharp pain in my knee from time to time, but this went away with improved muscles. With the seat at an angle, I think it was too much today, but I will see if it improves things.
