IMS versus Standard Baskets
I have been using the IMS 58mm H70 2T 26.5 M which holds 22 grams filling to the top (volumetric) and evening then tamp. Very reproducible pours.
I then measured the weight doing the same for the Wega portafilter and basket that came with the machine 18g. Interestingly only 2-3 notches on the Robur coarser, I thought it might be more.
I ordered the IMS but 24.5mm high and will try that.
I know a lot of people would do it by weight but I have it all worked out for the Robur. The only reason I go back to the standard baskets is to reduce the caffeine intake which is always a good thing.
The pour is great for both baskets. It is just always an interesting discussion to have though as everyone does things differently.
I don't want to use single baskets, in fact, I should get the new basket in a few days so will post again when I have tried that out.
I'm also using a "small double" basket for the same reason. It's only 20mm tall and I'm dosing 16.5-17.0g into it and getting good results with a 25ml extraction. Its not IMS but a generic one I picked up quite a few years ago at my local (previous 1st sponsor but no longer sponsor) shop.
I've also got a 23.5mm Pesado (by IMS) rated at 17g but I found I needed over 20g to get the required dose for my E61 machine (5c test), so it stays in the coffee parts box. I don't over-dose my shots and my machine has a standard E61 GH, so I'm a bit disappointed that the rated grams was so out of whack with my setup. I initially tried exactly 17g and when tamped, it barely came up to half way up the basket, so was way off.
