I got the 5033-03 in the last drop, and I like it a lot. have some other Spinnakers, and like all of them. I couldn't find the 5033-05 model on the Spinnaker website - how come?
AmitY"..not to mention the SP-5033-04, SP-5033-05, and SP-5033-06 styles are only available here on Massdrop"
It's in the first paragraph of the description.
