I don't know about anyone else, but racing outside in winter just doesnt work for me anymore....even on astro as the cars get filthy, and your thumbs refuse to work (i am doing electric btw). This is only my opinion, but i know other electric drivers feel the same.
I would be happy to race outside at around march/april, and would like to help with suggestions for the tenth track, in terms of layout surfaces and improvements! Might be worth trying to make the tenth track more all year round (are you putting astro on the tenth track? This isn't clear?). If you do get some astro down, try seeing if you can get a special meeting(s) added to the mam, so you dont clash...just a suggestion
I would not be happy racing my 10th buggy on the eighth track either (this is what i understand might happen, correct me if I am wrong).
Good work so far though and hope you have success with your winter series venture
