thought I had posted a response yesterday but don't see it here so I will again say thanks very much everyone for your helpful responses. The majority of your comments are consistent with views of my local peeps as well. I am going with the majority. Going to finish off that NSR and give it a try. Doubt I will outgrow it, at my age i am probably not going to get much faster, but it won't stop me trying.

Again, thanks everyone. Maybe I'll post some pics once it is all done.
