Hello Lou,
Without a doubt textiles are the best for winter. I've been riding for ever so really like my leathers, but at the end of the day you have to be warm and comfy.
All good advice in the postings so far, but here are a few more pointers.
If you are warm, dry and comfy you will be a safer and more concentrated rider.
Buy absolutely the best you can afford, and try it on. Then adopt your riding position: Does it cut you in half? Does the Jacket ride up over the top of the trousers? Is there room for layers whilst still not becoming tight? Don't be ashamed of squatting in the shop!
Cannot emphasise more strongly the returns policy that Geoff spoke about.
Heine Gerrick is good.
I use Rukka, whic is Uber-costly and even better.
Have a chat with Ollie at Motorcycle Essentials in Cannock (Not far from you) I've dealt with him many times. Honest and reliable kit. A very nice fellow ( and feel free to say I told you that...)
Any other questions, PM me.
