Until recently, I would always have supported the freedom to buy and use 'the best' controller 'you' can afford. All the bells and whistles 'you' like and the more adjustability the better.
But recently, I have been compelled to consider a different angle.
It was very sensibly put to me that, if a bunch of people with a variety of disposable incomes want to enjoy FAIR and enjoyable racing together, yet they still permit 'sky's the limit' expenditure on controllers, this has near as dammit the same ability to disrupt the group as allowing unlimited mods to the cars. Hmmm!
I have to admit the fellow made an excellent point.
There would be no problem with open racing (depending on the rules as always), but in a friendly group environment it could easily result in the group falling apart. Just to clarify - if 'you' can afford an all-singing all-dancing DiFalco, for example, should 'you' be allowed to use it in competition with a bunch of your buddies who can't? If you insist, you are going to pee them all of them off and you may end up witth no one to race! Conversely, if they insist, they are going to pee 'you' off - all that money and not be allowed to to use it? Come ON chaps, you have to be joking!
I haven't made my mind up, but it's worth some thoughtful consideration, I believe.
