Anyway, I've now ordered a selection of 3/4s from different manufacturers, and will see which is the least worst. Maybe Pearl Izumi have abandoned their 'flattering' waistband folly... I know I get on with their pads reasonably well.
Jinxed it.
Instant review:
Pearl Izumi Women`s Escape Sugar Cycling 3/4 Tight(JH1118): The cheaper material, rather than that excellent double-thickness stuff that goes blotchy with age rather than transparent. Sensible shape, grippers are good, waistband isn't a disaster. They've used a dubious looking piece of felt as a pad that looks distinctly non-recumbent-friendly, but is probably fine when used with a saddle.
Altura Women`s Airstream 2 3/4 Tights (AL32WAIR): Couldn't get into them because calves. Material becomes very transparent under tension. Not convinced by the shape of the pad.
Endura 8-panel Xtract Gel Knickers(E4015): Enormous. Thick wintery material. Thin elasticated waist may be an issue. My overall impression was 'cheap'.
Giant Liv Beliv Womens Knicker(86000077): Waste of time; no leg grippers. Good use of
PURPLE.
Gore Power 3.0 Women's 3/4 Tight: This one may be a winner. Known-good pad, sensible waist, the rainbow cuffs contain silicone grippers and look enough like a pride flag that they're not totally embarrassing. Complicated panel structure to make your quads look enormous.
Endura Hummvee 3/4 2 Womens Short(E6107BK): This was optimism, as the last time I bought some Endura baggies I happily spent the weekend wandering around the York Rally in them and then discovered there wasn't enough room around the quads to actually ride a bike (they don't do a larger size, and the men's ones don't have room for an arse). These ones seem a little bit baggier
[1], so I'm going to hang onto them, if just for pootling to the shops and stuff. Saves wear on the unobtainium lycra.
