i've been using 2" straight to the wand for years now and honestly can't say it is any bother at all, you soon get used to it and there is a definate increase in 'suck', hydramaster do a 1.75" wand with a 2" top for the hose to go straight onto. your other options for a 2" wand is the greenglide wand also from hydramaster if they still sell them, otherwise, it would have to be an import from an american source,
