Hi, I just noticed on Beini's etsy site that there is a 'new and improved; version of the 355 bulk-filler in some colorways. Anybody have an idea about what is different and what issue it addresses? I held back from the original bulkfiller due to mixed reviews on ease of use and opted instead for several of 456s and 500s and now a 492 as well (all brilliant). Might pick up one this time. https://www.etsy.com/shop/PENBBSOfficialStore?ref=simple-shop-header-name&listing_id=802394863§ion_id=25398175 Also to those who have a 355 - is it very difficult ascertain whether one got a good fill if one has a opaque resin body? - for example, I thought an opaque body will be less than ideal in a 500 due to the new system; but I took the chance on an autumn and it has not been a problem.
