Just finished going around 18 on Thornberry Creek and plays/looks great AND it's only 169 Mb. Don't know why other designers can't put out leaner courses - so many top heavy (for those of us with small SSD's 250Gb). My policy is any course over 350 Mb I take notes on and then take it off SSD.
I think I asked this before but forget answer. I was thinking of getting a large thumb drive (over 100 Gb) to put the over 350Mb courses. Then I could use thumb and SSD - can I use both and somehow switch between the two. My gut tells me NO.
