A new one for 2021 from Prestigious Pyrotechnics ... the landed product will last at least 50 seconds Name - PROLIFIC Shots - 100 Shots Tube - 25mm NEC - 998g RRP - TBC
I think 25mm tubes are possibly the optimum size. There is usually a noticeable difference between 20 and 25, but less so between 25 and 30. For the extra cost involved in 30’s ..?? (Another cracking piece, that one).
Purely down to area I guess Paul? Ignoring depth / volume, 20mm to 25mm tube is a 56% increase, then on to 30mm is only a 43% increase, so less of a change if that makes sense. My admittedly very basic knowledge of mechanics makes me think there would be massively more edge effect / drag with 20mm but I may be very wrong there... Coupled with the quality of effects we’re now seeing squashed into 25mm it really does seem to be a sweet spot as you say. I’m sure others more knowledgeable may contradict me though!
I have been saying this for a while now and going back a few people didn't really get what i meant but for me the more i have delved into bespoke products the costs v effects/tube size etc argument is won by 25mm. Just my opinion i know but i honestly feel it is the sweet spot as you would say
