I used Wintesla for my 6" secondary - 15/60 NST/01. mfd cap
coil specs and it originally called for 66' feet of 1/4" tubing with 
my initial plan of using a 15 degree primary. Since I went to the 
flat spiral primary, it dropped it down to 62 feet of tubing. I wound 
the primary with my girlfriend's help a few days ago and Wintesla 
was off by a few feet. It didn't matter though as I had bought 
two 50' coils of tubing and just used a nail with the head cut off to 
splice the additional 12 foot section together. Worked real good 
and the primary came out very well. Thank gosh for HDPE. :-) 

They might make 100' coils of 1/4" refrigeration tubing, but I've 
never seen them, just the 50 foot coils.
