Experience - yes, lots! I started in the 1980s with IR Ektachrome false colour film, then countless rolls of Kodak HIE mono film, and a few others, then digital with a converted Canon DSLR, then I went to the Fuji X system which is IR sensitive naturally which makes life a lot easier.
A lot depends on what it is about the IR look you like. Digital IR is not the same as film IR, and if I had the patience and could get the film, I'd probably shoot IR on film as I love the look of halation (a 'fault' of IR film, and development method where the emulsion 'spreads' the light areas into the dark areas due to reflections - it can be minimised by careful development) then digital IR doesn't give you that, though you can emulate the effect in post processing. The blurry cloud look is due to the inevitable long exposure times necessary with film, but converted SLRs are usually sensitive enough to use hand held.
It's also 'seasonal' with best results in the spring on sunny days so you've missed it in the UK, though you can get good results at any time of the year. i usually do oe IR project each year, though being in shielded isolation this year has limited things. This is from last year:

If you want to dabble then either grab a used converted DSLR to match any lenses you have, or if you have a Fuji X camera buy a 720 filter and a tripod and off you go. I have a selection of filters right down to a 950 which is essentially un-useable, 850, marginal, 760 ok, but I use 720 more than any of them as you can still see through the viewfinder and can hand hold at high ISO on a sunny day.
