There is no doubt it has been a massive step for some but the effort and willingness to learn and improve has never faltered.Included in the group are Edinburgh Elite Development Players (EDPs) Phil Cringle, Neil Irvine-Hess, Jamie Farndale and Magnus Bradbury, along with Melrose winger Damien Hoyland who will join the club on a full-time basis next season. Glasgow EDPs Gavin Lowe and D’arcy Rae are included, along with Currie trio George Horne, Grant McConnell and Ruaraidh Smith, the latter of whom handed off four defenders to touch down against Glasgow Warriors at last Saturday’s Melrose 7s.This is the first of three training camps prior to a squad setting off for the southern hemisphere, where they’ll take on South Africa (Monday 2 June), Samoa (Friday 6 June) and New Zealand (Wednesday 10 June) in the pool rounds. In last year’s tournament Scotland finished in tenth place, beating Samoa in the early stages. England were eventual winners, defeating Wales in the final in north-west France.New Zealand is hosting the tournament for the first time, with matches at QBE Stadium in North Harbour and ECOLight Stadium in Pukekohe and the final to be held at Eden Park, Auckland. Lineen added:We all know the challenge that awaits us in New Zealand, but what a fantastic opportunity for the 28-man squad that will head down under to face New Zealand, South Africa and Samoa.Scotland under-20 squad for April campChris Barnes (Glasgow Hawks) * Magnus Bradbury (Boroughmuir/Edinburgh Rugby) ** Lewis Carmichael (Melrose) * Gabriel Carroll (Loughborough University) Ben Chalmers (Melrose) Scott Cummings (Kelvinside Academy/Glasgow Hawks) * Jack Cosgrove (Worcester Warriors) Andrew Cramond (Aberdeen Grammar) Phil Cringle (Edinburgh Accies/Edinburgh Rugby) ** Jamie Farndale (Edinburgh Accies/Edinburgh Rugby) ** Cameron Fenton (Strathallan/Howe of Fife) * George Horne (Currie) * Damien Hoyland (Melrose) * Blair Hutchison (Melrose/ Loughborough Uniiversity) Neil Irvine-Hess (Watsonians/Edinburgh Rugby) ** Sam James  (London Wasps) Ben Johnston (Marr) * Gavin Lowe (Glasgow Hawks/Glasgow Warriors) ** Murdo McAndrew (Clermont Auvergne) James Malcolm (Ayr) * Grant McConnell (Currie) * Isaac Miller (Loughborough University) Sam Pecqueur (Edinburgh Accies) Gavin Parker (Exeter University) D’arcy Rae (Ayr) ** Angus Rennie (Aberdeen Grammar) * Tommy Spinks (London Scottish) Ruaraidh Smith (Currie) Ben Vellacott (Hartpury/Gloucester) Sean Yacoubian (Glasgow Hawks) Glen Young (Newcastle Falcons) Ruairidh Young (Edinburgh Accies)* member of Scottish Rugby’s Regional Academy supported by sportscotland Institute of Sport  ** Elite Development Player 2013/14
